You would probably be flamed for saying this by anyone who subbed for the current version for the longest time. The new version is being delayed long enough and they're already aiming for a summer release. SE is still running a risk of failure while trying to save this game in such a competitive market..

This is SE. Their game will have the classical MMO formula. If you're a seasoned mmo player, you might be tired of it and that's fine. They already said they're going to be tweaking the battle dynamics throughout beta testing, but expecting them to revamp or completely overhaul a core game system just shows how unrealistic your expectations are for a game with such a troubled history that could have been scrapped just as easily.

They're listening to the wrong fans. That gameplay looks bad. No one likes playing a spam spam spam game. The gameplay I've seen is full of magic flowing around, a bunch of spam attacks. That's not a fun a game. A fun game is one where you need to think.

For the record, "spam" combat isn't as dull as you make it sound.
Maybe from a PVE perspective.
But waiting on cooldowns to reset on special abilities by spamming attacks to cause confusion is an incredible strategy in PVP and can throw off your opponent easily. But it has to be done wisely, or you may miss your chance to link it to special attacks.

For PVE, I think it's always going to be dull no matter what you do.
After you "absorb" all the mechanics and "learn it, you'll just do everything automatically/without thinking regardless, unless you're playing an RTS game, where the AI of your opponents can overpower you.

Back on topic; I am not playing the current phase, mostly 'cause SE can't verify my credentials (Even though they're all exactly as they were). But the few friends who are playing the current phase, keep giving me mixed reactions.
I am hoping it all ends positive in the end.

That's an incredibly difficult thing to balance for end game content, specially if raids are involved.
If it's single player, then it's easily balanced, the same way most normal RPG's are. But regardless, if you're going to make difficult PVE content with more than one person in mind; it's going to be tough to do.
TERA was close on that regard; but they blew it for more than obvious reasons. But even there, once you mastered your class, you could press buttons automatically.

Then again, I felt the same way with most classic and even recent FF games, except maybe Tactics (Though even that was still kind of easy to predict; despite the enemy AI being so random).
But if you were to throw in a second person; or more realistically, 5 or more; well, those count as random inconsistencies as well.

As far as the "spammy and horrible combat" concerns, keep in mind this is low level alpha footage. What you are seeing in these videos is in no way representative of how the game might actually play out at higher levels in the hands of actual players and not short teaser videos.
